Emergency! S05 E07 Pressure 165

"Squad 51, this is Rampart. Continue to monitor patient and transport immediately."

Once again, the others rib Johnny about his cooking, so he sets out to prove he can make a fine meal - and of course gets interrupted and the meal ruined. But he and a doctor treat a diver suffering pressure injuries using a decompression chamber. He and Roy also deal with a famous chef who refuses to admit he accidentally set his own kitchen on fire. A dust explosion and a gunshot wound finish out the story.
